Because Brazil has continental dimensions, news is the key tool to integrate all regions of the country and is the main GLOBO production, with a total of 58,000 hours per year produced by 3000 journalists.
GLOBO’s newscast schedule is divided into local and network newscasts from morning to evening. Each affiliate produces up to 13 hours of weekly news for its districts and sends content to network headquarters to be broadcast.
Traditionally, content was exchanged via microwave or satellite links in real time, which means booking complexity and limited time windows in expensive communication channels. But since July 2007, GLOBO and its affiliates have operated a customized system to exchange off-air news content using IP technology over a robust and private broadband network.
This Intelligent Tool shares the content produced by each affiliate based on 24/7 operations. All participants are able to search, select, watch low-res content (LR=WM@256Kb/s) and retrieve high-res files (HR=WM@4Mb/s). The system provides security settings for protecting confidential information and defines rights management for content usage. Each affiliate can automatically manage the files’ download priority according to its program guide. Other important features include archive control, partial retrieval, customized reports and peer-to-peer sharing between affiliates.
The system architecture is comprised of an SQL redundant central database, a redundant central DNS Web server, workstations and MPLS network technology.
All content shared in the new system is available 24/7 over a reliable private network with firewall and cryptography protections, which equates to three times the savings when compared with the booked and rented A/V satellite or microwave links.
The application has a user-friendly Web GUI for the journalists, who can watch the low-res clips before asking for the high-res content, which is transferred at least two times faster than real time.
